http://bugzilla.xensource.com/cgi-bin/bugzilla/show_bug.cgi?id=20 ------- Additional Comments From kaf24@xxxxxxxxxxxx 2005-05-08 08:49 ------- If you're trying to work out how the crash occurs you want to disable ptwr batching in do_ptwr_fault() in arch/x86/mm.c. To do this, turn the '#ifdef __x86_64__ goto emulate' into '#if 1 goto emulate'. This will cause a crash within XenLinux at the very instruction that writes a bad page-table entry, rather than crashing sometime later when a batch of pagetable updates get validated. Much more useful! ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. _______________________________________________ Xen-bugs mailing list Xen-bugs@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-bugs |
